` WILLIAM JOSEPH LYNCH, OF GYIVIEIE, QUEENSLAND, AUSTRALIA.

JGGER.

Application filed December 1, 1921.

To all whom t may concern:

Be it known that I, VViLLiAM dosnrri LYNCH, subject oi' the King oi' Great Britain, residing at Gfympie, Queensl nd, Australia, have invented certain new and useful Improvements in diggers, of which the followingisla specification. j j

This invention relates to an improved jigger iter use in separating ore particles from stone particles or gangue in an eilicient and expeditious manner.

In carrying out my invention I provide two hutches, or perhaps in some cases a single hutch, having sloping bottoms and the usual outlets. Suspended in these hutches from rockers pivoted above is a pair o'll jigger boxes fitted with screens or sieves. Intermittent vertical movement is imparted to the jigger boxes by any suitable means. The hutches are each divided into two compartments and outlet shoots on the ends ot the jigger boxes deliver the stone particles or gangue into one compart` ment, while the ore particles are delivered through the screens or sieves into the other compartment. The ore and stone particles are delivered from the respective compartments as and where desired.

In order that my invention may be better understood I will now describe it with the aid oi' the accompanying drawings, in which- Fig. l is an end. elevation (part in section).

Fig. 2 is a side elevation (part in section).

In carrying out my invention I construct a pair oi hutches A, carried by a frame B and having sloping bottoms A1. Outlets A2 A3 lead as 'and to where desired. I may in some cases use single hutches.

Pivotally carried bythe trame B are rocking beams C which in turn pivotally carry the two pairs of yolies D. The rocking shaft C1 which carries the rocking beams i may be pivoted as shown in the drawings or the pivots C2 may be carried by the side members of the traine B.

p From these yokes D jigger boxes E are suspended as by rods El or otherwise, stretching screws E2 o-r other means being provided so that the level of the boxes E may be properly adjusted. The jigger' boxes E are fitted with the usual screens or sieves and each have at one end an outlet E3, ad-

justable as to height. I prefer that the jigger boxes E should be arranged in pairs so that the one counterbalances the other, although it is possible that a single box may be arranged: in which cases the rocking beams C would be suitably balanced.

The hutches A are fitted with partitions F just beyond the end of the jigger boxes E which divide it into two compartments F1 F2 and the outlets E3 from the boxes E slope down over the tops of these partitions F.

Motion is imparted to the jigger boxes@ by means ot the eccentric H, driven 'from any cource oit' power supply, eccentric rod I-Il, slide rod II2 and lever II' carried by the rocking beams C. Movement ot the lever I-I" on the slide rod II2 is provided between the collars, shoulders or nuts Ht which may be adjusted as desired, so that intermittent action is given to the rocking beams C.

In constructing jiggers according to our invention we would vary the constructional details as found desirable, the material used being that best suited for its purpose.

ylfhe operation of my invention is as follows The eccentric I-I having been set in motion, the collars, shoulders or nuts H* on the slide rod H2 operate on the lever H3 thus rocking the rocking beam C. An up and down movement is imparted to the jigger boxes E and as intermittent movement is given to the lever H3 by the slide rod H2 a jerky action is given to the jiggers E. rlhe ore particles fall through the sieve or screens in the bottom of the jigger boxes E into the compartment F1 ot the hutch A and the stone particles or gangue passes out over the outlets E3 into the compartment F2.

Having now fully described and ascertained my said invention and the manner in which it is to be performed, I declare that what I claim is l. A jigger including a frame, a plurality of hutehes supported by the trame, a partition arranged in each hutch and dividing the interior ot the hut-ch into two compartments, a box arranged in each hutch and adapted to discharge ore into one or' said compartments ot the hutch in which the box is arranged, a chute `tor each box adapte'd to discharge stones and gangue into the other compartment of the hutch in which the box is arranged, extensible rods supporting each of said boxesq yolres connected to said rods, a rocking beam carrying said yokes, and means for rocking said beam and jarring' said boxes.

2. A jigger as claimed in cla-iin l in which the last mentioned means includes a slotted post connected to said beam, a bar extending through the slot ot the post, abutment members arranged in spaced relation on the bar and adapted to alternately contact with the post, and means for reciprocating` said bar.

3. jigger including a plurality of parallel hutches, each provided with a transverse partition dividing the same into a plurality of compartments, outlets for each ot' said compartments, a trame extending above said hutches, a rocking beam pivotally mounted intermediate its ends on said frame, yokes pivotally connected intermeture, a reciprocating link extending through said aperture and havin@ spaced abutments adapted to intermittently strike the post when the last mentioned link is reciprocated, and means Ytor reciprocating the last mentioned link.

In testimony whereof I aliix my signature.
